Screen wont turn off when I close laptop lid

I have recentley installed Windows 7 RC. Since installing it, I have noticed that when I close my laptop lid, the screen stays on. How do I get the screen to turn off without going into sleep or hibernate mode? I've tried messing around with the power options but nothing seems to work.

When I am downloading something I usually close the lid and let it get on with it. If I was to put it in hibernation, I wouldnt be able to download anything. When I am at home, I usually just have the laptop connected to mains and have it on all the time but prefer the screen to be off when Im not using it.

I was on Windows XP prior to that and the screen turned off when I closed the lid.

I recently installed Windows 7 drivers for my graphics card, im not sure what the situation regarding the screen was before that as I hadnt closed the lid before I installed the new drivers. I've got ATI Mobility Radeon X1300 if that helps.

My download speeds arent slow but like I said, I usually just leave my laptop on when I am at home even if its not downloading or running anything.

In the power options, go to Change Plan Settings and theres an option to 'Turn off the display' after a certain amount of minutes! Dont know how I missed this the first time! Hope this helps anybody else with the same issue!
